如何在Asp.NET的代码隐藏中访问PagesSection属性

using System.Web.Configuration;

// 获取Pages配置节
PagesSection pagesSection = ConfigurationManager.GetSection("system.web/pages") as PagesSection;

// 访问PagesSection的属性
bool enableSessionState = pagesSection.EnableSessionState;
bool enableViewState = pagesSection.EnableViewState;
int maxPageStateFieldLength = pagesSection.MaxPageStateFieldLength;

// 修改PagesSection的属性
pagesSection.EnableSessionState = true;
pagesSection.EnableViewState = false;
pagesSection.MaxPageStateFieldLength = 4096;

// 保存配置文件
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
config.Save(ConfigurationSaveMode.Modified);
